Additional information can be found in the World Health Organisation (WHO): Guidance on regulations for the Transport of Infectious Substances 2015-2016

For transport of infectious microorganisms, commercial, certified UN packaging is required. UN3373 Packaging Requirements for Biological and Infectious Substances outline the regulations for UN3373 Medical Packaging.

Sending microorganisms in plastic Petri plates should be avoided, if possible; the samples are at risk of being damaged during shipment and contaminating the package. Screw-capped glass or plastic tubes that may be sealed to avoid leakage during transport are ideal.
